That's a good question (that I hadn't thought of, and to which I don't have an anaswer), but... If the kit does utilize a burn string, maybe we can look forward to future Estes boost-glider (B/G) kits (similar to the original-design Renger Sky Slash, which had pop-up elevators) and/or rocket glider (RG) kits that use burn string-retained sliding wings or motor pods, and:
With today's laser-cut sheet balsa (and laser-cut basswood, fiber [beveridge board], and even thin modeling plywood sheet parts), and molded plastic "fulcrum" or interface parts such as rotor hubs, hinges, and motor pod lug/hooks, it is now possible to produce helicopter, B/G, and RG kits that are relatively easy to build and reliable to operate, compared with such kits of a generation ago. Back then, many of these parts had to be cut, shaped, and size-matched by the builder, which made the models tricky to build and more likely to fail in flight. One early (1973) step in the direction of today's kits was Centuri's Hummingbird boost-glider (see: http://www.ninfinger.org/rockets/no...a/73cen70e.html ), which had all-die-cut fiber wings and tail surfaces. |
